The presence of too much algaecide can lead to a foamy pool water. Small bubbles will begin to be produced as the water is pushed through the return jet and back into the pool. Do not confuse these bubbles and foam with another common problem, which is air in your pool lines.
If you add algaecide, keep in mind that some algaecide contains copper, which can actually make a pool cloudy. If the cloudiness persists 24 hours after shocking, then it's possible that you used a poor-quality chlorine shock.
While shocking and adding algaecide is effective in getting rid of algae, it should not be done together. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM.
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.
Algaecide should be added to your pool water on a weekly basis. Preventing algae is the key to fun in your pool. Algaecides act as a backup to your normal sanitization program and prevent algae from starting and growing in the pool. Algaecide should be added after every shock treatment.
ADD POOL CLARIFIER
If your water is still green, wait another 24 hours and redo the steps from Days 1 and 2. Now is the time to add Pool Clarifier and let it circulate for 12 hours. This will clump the algae together into vaccumable pieces.
The algaecide in the kit can cause some foam if there is no algae in the pool to destroy – it lingers around with nothing to kill. Spring time algaecides use surfactants to work and these molecules can react with agitation to cause froth.
Algaecide can cause your pool water to thicken and can cause pool foam.
Finding foam in your pool usually means there's a high organic load in the water. In other words, more organic material than can be dissolved in the water, or eradicated by sanitizer. This causes the water to “thicken.”
It's important to know that using pool shock and algaecide together can create bad chemical reactions if you don't take the necessary precautions. Your chlorine levels won't return to normal right after you shock your pool anyway, so we recommend waiting at least 24 hours to add algaecide.
When closing and winterizing your pool, it is important to remember to balance your pool water's chemistry prior to closing and don't forget the algaecide. Algaecide is simple and effective with one quart of winter algaecide typically enough to treat 20,000 gallons of water all winter long.
Chlorine combines with the algaecide ingredients and renders them useless. The best time to introduce an algaecide , which functions best as a preventative, is after you've shocked the pool and the chlorine level has fallen below 5 parts per million.
There are a few different types of algaecides that contain various chemicals to suppress and fight off algae. Many of them include copper or copper sulfate. It's this copper that oxidizes in the water. And when copper oxidizes it turns a green color causing your pool to look green.
Let the water circulate for at least two hours.
Circulate the water for about 2 hours to ensure the flocculant is fully mixed in, then shut off your pump and let it sit overnight. During this time, the chemical will start to bind the particles together and settle them to the bottom of the pool.
pH Balance and Chlorine
Algaecides do not directly affect the pH balance in your pool, but too much algae will raise the pH level. By eliminating algae, the algaecide helps return pH levels to normal. Algaecide also works together with chlorine, helping the chlorine to be more effective against algae and bacteria.
Air bubbles in your pool mean that air is being sucked into the line on the suction side of the pump. It's likely happening because of one of these issues: The pool water level is too low. The strainer pot lid isn't on tight or its O-ring is loose/absent/compromised.
High Bather Load
On top of that, skin oils, sweat, (and urine) also build up with lots of pool guests. This is a good recipe for foam buildup, especially if you don't test and treat your water soon after your party leaves. Untreated water after a high bather load often results in foam and cloudy water.
Swimming pool foam can be a huge distraction in and outside of your pool. Foam, or bubbles, make the water feel sticky and can make swimming uncomfortable for some. Good news for the kids, though, a foamy pool is safe to swim in. Still, we always recommend getting rid of the foam as soon as possible.
Swimming pools use chlorine as the main sanitizer. This chemical is responsible for keeping the water free of bacteria, which helps prevent algae and other problems associated with a dirty pool. A film can form on the water from a combination of body oils, lotions, and dirt that build up due to heavy usage.
If you feel sticky after swimming, it's likely because your pool is dirty and needs treatment. Stickiness can also be due to pH imbalances, chemical changes, or various contaminants in the water. Taking a shower can help reduce feeling sticky after swimming.
Baking Soda and Green, Blue, or Yellow Algae
You'll need to use an algaecide to kill the algae and superchlorinate your pool to clear the water. After this treatment, test your pH and alkalinity and add baking soda to raise alkalinity to at least 100 ppm and pH to between 7.2 and 7.8.
To treat pool water made cloudy by a lack of chlorine, simply keep adding chlorine to the water until the water maintains a chlorine residual of 2ppm or more. If you suspect that the cloudiness is caused by poor water balance, simply add a pH/alkalinity decreasing chemical until the water comes into balance.
So unless you're dealing with mustard algae or black algae, leave the algaecide on the shelf and get ready to shock the heck out of your pool. But when dealing with regular ol' green pool algae, chlorine is your best bet to kill it dead.
